Research on Network Security Protection Mechanism System Based on Blockchain Technology

This paper proposes a network security protection mechanism system based on blockchain technology, aiming at improving network security and data integrity. Firstly, it introduces the application background and status quo of blockchain technology in the field of network security, and expounds the problems and challenges existing in the traditional network security protection mechanism. Then, the modeling process of dynamic data security storage based on blockchain is described in detail, including key technologies such as data encryption, distributed storage, and access control. Then, an ownership state transfer function is designed to realize ownership management and state tracking of data. In order to verify the effectiveness and feasibility of the system, a model simulation experiment is carried out in this paper. The experimental results show that the system can significantly improve the security of the network and the integrity of the data, and effectively resist all kinds of network attacks. In addition, the system has good scalability and flexibility, and can adapt to the needs of different network environments and application scenarios.
